Aluminum oxide is decomposed using electricity to produce aluminum metal. Hm grams of aluminum metal can be produced from 100.0g of Al2O3?
2Al2O3--> 4Al+ 3O2
If 2Al2O3 --gt; 4Al+ 3O2; So, first of all we can find amount of substance of Al2O3: n(Al2O3) = m(Al2O3)/M(Al2O3); M(Al2O3) = Ar(Al)*2 + Ar(O) *3; M(Al2O3) = 27*2+16*3 =...
